With a hard edge original music, this trio has put together one of the best bands around. With their performances From Orlando... Topic: Thrust SuperSonic
The center used an F-18 as the High Angle-of-Attack Research Vehicle in a program from 1987 to 1996. Fresh from its reconstruction (it was assembled from many parts and affectionately dubbed "Silk Purse"), the aircraft was extensively instrumented both to record data at high angles of attack and as a means of developing flight research techniques in high-alpha flight. Researchers also conducted visual studies of the airflow over various parts of the aircraft at high alpha using tracer...

A series of progressively finer grid systems to calculate the single jet in cross-flow experimentally measured were employed. The experimental measurements provide a collection of velocities, turbulence intensities, and jet concentration profiles with measurements of the inlet field. The use of a series of progressively finer grid systems allows a differentiation between numerical errors and the hydrodynamic modeling assumptions embodied in the 3D combustor code.

The paper presents reliability assessment results for the robust designs under uncertainty of a 3-D flexible wing previously reported by the authors. Reliability assessments (additional optimization problems) of the active constraints at the various probabilistic robust design points are obtained and compared with the constraint values or target constraint probabilities specified in the robust design. In addition, reliability-based sensitivity derivatives with respect to design variable mean... Topics: TURBOJET ENGINES, DUCTS, SHROUDS, PRESSURE MEASUREMENT, THRUST
"Thrust" documented the street music scene in Florida from 1989 to 1993 out of Tampa Bay, FL. This monthly free publication brought "...a new breed of rock journalism that is unprecedented in the Tampa Bay area -- hard hitting and deep pounding." Topic: Thrust magazine Florida Tampa Bay bi-coastal
This paper presents an overview of an ongoing research and development effort at the NASA Ames Research Center to create an autonomous control system for an internal spacecraft autonomous mobile monitor. It primary functions are to provide crew support and perform intra- vehicular sensing activities by autonomously navigating onboard the International Space Station. We describe the mission roles and high-level functional requirements for an autonomous mobile monitor. The mobile monitor...

A multi-body flight simulation for the Mars Smart Lander has been developed that includes six degree-of-freedom rigid-body models for both the supersonically-deployed and subsonically-deployed parachutes. This simulation is designed to be incorporated into a larger simulation of the entire entry, descent and landing (EDL) sequence. The complete end-to-end simulation will provide attitude history predictions of all bodies throughout the flight as well as loads on each of the connecting lines....

An acoustic theory is developed to determine the sound transmission and attenuation through an infinite, hard-walled or lined circular duct carrying compressible, sheared, mean flows and having a variable cross section. The theory is applicable to large as well as small axial variations, as long as the mean flow does not separate. The technique is based on solving for the envelopes of the quasi-parallel acoustic modes that exist in the duct instead of solving for the actual wave, thereby...

The longitudinal stability and control characteristics of a B-29 airplane have been measured with a control surface booster incorporated in the elevator-control system. The measurements were obtained with the booster operating to provide various control-force gradients and various maximum rates of control motion. Results are presented which show the effect of these booster parameters on the handling qualities of the test airplane.

Experiments were conducted to study the effects of spray trajectory angles upon heat flux for flat and enhanced surface spray cooling. The surface enhancement consisted of straight fins machined on the top surface of a copper heater block. Spray cooling curves were obtained with the straight fin surface aligned both parallel (axial) and perpendicular (transverse) to the spray axis. Measurements were also obtained on a flat surface heater block for comparison purposes. Each copper block had a...

Strength, fracture toughness and fatigue behavior of free-standing thick thermal barrier coatings of plasma-sprayed ZrO2-8wt Y2O3 were determined at ambient and elevated temperatures in an attempt to establish a database for design. Strength, in conjunction with deformation (stress-strain behavior), was evaluated in tension (uniaxial and trans-thickness), compression, and uniaxial and biaxial flexure; fracture toughness was determined in various load conditions including mode I, mode II, and...

The F-15 ACTIVE in flight over the Mojave desert during a High Stability Engine Control (HISTEC) flight. The twin-engine F-15 is equipped with new Pratt & Whitney nozzles that can turn up to 20 degrees in any direction, giving the aircraft thrust control in the pitch (up and down) and yaw (left and right) directions. On March 27, 1996, NASA began flight testing a new thrust-vectoring concept on the F-15 research aircraft to improve performance and aircraft control. The new concept should...

The flow in the divergent part of a highly over-expanded nozzle suffers strong instability due to formation of shock waves which causes mixing enhancement in the flow and destabilizes the shear layer adjacent to it. The code FLUENT has been used to simulate the flow of two different viscous fluids (air and hydrogen) through five different ConvergentDivergent (C-D) nozzles of varying area ratio and exit angles. 2-D steady state RANS equation has been simulated for both inviscid and viscous...
